This invention has relation to multi-color thread sewing machines and which consists in the novel features hereinafter described and claimed.

The object of the invention is to provide means which may be permanently applied to a sewing machine or which may be in the form of an attachment and adapted to carry threads of difl erent colors with means for guiding and feeding the respective threads to individual needles, and means for holding these needles conveniently at hand when not in use, and means for holding bobbins, each having a different color thread, so that any particular bobbin may be used with a needle threaded with a corresponding thread as that carried by the bobbin.

This machine is especially adapted to be used to advantage in repair shops and other places where demand is made for repeated shifting from the use of one color of thread to another, and the device is of such convenient arrangement that much time is saved by having the difierent colored threads ready at hand upon the machine, thus eliminating the delay heretofore experienced of hunting through drawers and racks to find particular threads to be used upon certain alteration and repair jobs. In the present invention the 30. needles and the bobbins are always threaded and ready at hand for use.

In the accompanying drawings:

Figure 1 is a side elevational view of the arm of a sewing machine illustrating the multi-color thread device applied thereto.

Figure 2 is a top plan view of the same.

Figure 3 is a front elevational view thereof.

The parts of the multi-color thread sewing machine include a spool holder applied to the upper side of the arm 1 of the sewing machine. Said spool holder consists of a plate 2 attached to the upper side of the arm 1, there being a series of upstanding spaced spindles 3 mounted upon the plate.

A bar 4 is pivoted at the upper end of each of the spindles and when the bar is swung into alinement with the spindle a spool 5 may he slipped down over the bar and the spindle and then the bar may be swung down over the spool whereby the same is held in held up against the bar 4. Each to prevent them from unwinding too rapidly position upon the spindle. i The lower end which surrounds'the spindle and bears upon the plate 2 so that the spool is resiliently spool 5 is wound with a diiferent colored thread, the

threads being indicated at 7. An arm 8 is attached to the forward side of thehead of the sewing machine and the said arm is provided with a downwardly curved end portion 69 9 having at its inner side a-series of recesses. 10. The recesses lead in from the inner edge of the curved portion 9 and are enlarged at their inner ends and each recess receives one of the threads 7. .When the threads 7 leave the spools 5 they pass through the recesses in the guide 11 located below the lower ends of the spools. From the said guide the threads pass down around a shaft 12 attached at the side of the head of the machine. A

series of concavo-convex disks 13 is mounted uponthe shaft 12 and the said disks are held by a spring 14 against the threads to provide suflicient friction upon the threads from the spools. "Each thread passes over a hook 15 located at the side of one of the disks 13 and from the hooks 15 the threads pass under a bar 16 mounted at the side of the head of the machine.

The lower edge of the bar 16 is located below the hooks 15 and consequently when the threads pass from the hooks to the bar they move downwardly and from the bar 16 the threads 7 move in an upward direction to the recesses 10 in the arm 8 hereinbefo-re described. A guide bar 17 is attached to the side of the head of the machine and said bar 17 is provided with eyes 18 through which the threads 7 pass. A bar 19 is mounted at the lower portion of the head and the threads pass under the said bar 19, when not in use. Each thread carries a needle 20 and. a needle rack 21 is mounted upon the head of the machine adjacent the bar 19, and the said needle rack is provided with a series of recesses or openings 22 each adapted to receive one of the needles 20 as best shown in Figure 3 of the drawings. w

The sewing machine is provided with a 100 take up bar 23 as usual and the said take up bar is provided at its free end with a recess 24 usually closed by a spring 25. The sewing machine is also provided with the usual needle shaft 26.

hen a thread having a particular color is desired to be used, that thread is removed from the recess 10 in the arm 8 which is holding the same and is inserted in the recess 24 of the take up bar 23. The needle which carries the said thread is removed from the needle rack and inserted in the shaft 26. Thus the needle having the thread with the desired color is in position to be used in the machine, and the needles upon the threads of diiferent colors are in the needle rack ready to be used in the event that the character of work to be done should require such use.

The table 27 of the sewing machine is provided with a glass slide 28 which normally closes the bobbin chamber of the machine. An operator may glance throughthe transparent slide 28 and observe the condition of the bobbins when the machine is in operation.

Having described the invention What is claimed is A multi-color thread sewing machine comprising a series of spool carriers mounted on the arm of the machine, each carrier adapted to receive a spool wound with a distinctive thread, an arm mounted upon the machine and having a recess for the reception of each thread, tension means engaging the threads between said arm and the spool carriers, a rack for retaining the end portions of the thread and means for guiding the thread from said arm to the rack.

In testimony whereof I aflix my signature.

CARL A. DICKEY.
